Hangs when powering up. Pushed the Power Button, LCD Screen says Loading, BluRay Splash screens appears on the TV, then it turns itself off. I have unplugged the player for 15 minutes, held down the Eject button to get the disc out. Now the LCD Screen says, Waiting. I've been waiting for 30 minutes now. This has occurred after viewing Race to Witch Mountain.

Vizio logo is an indicator that the tv is live n changes to white that the screen is on meaning if no change to white the smps switch mode power supply board ain't switching the mother board....diagnosis is its MOSFET transistors need replacement or the smps board n ya tv will be fine

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

> won't turn on

Remove the side-panel, and then press the ON button.
Do any fans start to turn? Feel any air coming out of the back of the power-supply?
Does pressing the button open/close the CD/DVD tray?
If not, then your power-supply has "blown", and must be replaced.

If the fans do turn, and the tray opens, but nothing happens on the screen,
e.g., no "splash" screen, nor any brief white-text "hardware-summary" appears,
then it's either the CPU or the motherboard which is the problem.

If you see the "splash" screen, or that "summary" screen, but Windows does not start to load, then the disk-drive either is not getting any power, or its "data" cable is not connected, or the disk-drive itself has "died".

It's time to take it to a qualified technician, for professional trouble-shooting.

Your power board got zapped you will need to replace it.

Turn ON the TV

While holding down the UP arrow button on the Remote Control, press the power button on the TV (hold for 10 seconds)

The TV will turn itself off, then back ON again.

Release the up arrow button. 

You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.
